INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Nov. 1 6, 1915.

Application filed July 7, 1913. Serial No. 777,612.

To all whom it may concern:

Be it known that we, ALBERT H. DE GAs- TON, a citizen of the United States, and FREDERIC MCLEAN, a subject of Great Britain, residents of the city of Sacramento, county of Sacramento, State of California, have invented certain new and useful I'mprovements in Internal- Combustion Engines, of which the following is a specification.

The invention relates to internal combustion engines and particularly to an ignition device for internal combustion engines operating on oil fuel.

The object of the invention is to provide a quickly removable and attachable igniter.

Another object of the invention is to provide means for holding the portable igniter in place, which is so constructed that the igniter may be securely fastened in the cylinder or quickly removed.

With these and other objects in view, as i will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, here inafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structures may be made Without departing from the spirit of or sacrificing any of the advantages of the invention.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a vertical cross section of the head end of the engine cylinder, showing the igniter of the present invention. Fig. 2 is a horizontal cross section of the head end of the engine cylinder showing the means of holding the igniter in place. Fig. 3 is an end view of the engine cylinder, partly broken away.

In internal combustion engines operating on oil fuel, ignition of the charge in the cylinder is often obtained by means of a heated igniter. It is evident that when the igniter is cold it is impossible to start the engine, and various means and methods have been heretofore employed for initially heating the igniter. When the igniter has become sufiioiently heated to operate the engine on oil fuel, the auxiliary means of heating are disconnected or thrown out of operation and the heat of combustion in the cylinder is suflicient to maintain the igniter at it may be heated to the required tempera-- ture at some external point, and inserted into the cylinder. It is evident that the means for securing the portable igniter in the cylinder must be capable of rapid manipulation, so that the igniter may be securely placed and the engine started before it cools.

In accordance with the present invention, the portable igniter 2 is arranged in the head 3 of the cylinder 4 in which operates the piston 5. The fuel injection nozzle 6 is arranged so that the charge of fuel is projected onto the tongue 7 of the igniter, which projects into the cylinder. The cylinder head is preferably formed with an inwardly flaring aperture 8 in which the igniter is arranged. The tongue of the igniter is of less diameter than the smaller end of the flaring aperture, and the igniter gaging in the .bifuicated clamp 13.; The

clamp is provided with apertur'ed bosses 14 at its opposite ends, through which pass the studs 15 which are screwed into the cylinder head. The clamp is held against the cylinder head by means of the nuts 16 engaging the studs. The aperture 17 in one end of the clamp is open at the side so that the nuts 16 may be released and the clamp swung about the other stud as a pivot to move the clamp out of its position in front 1. In an internal combustion engine, a

7 cylinder head having an inwardly flaring aperture therein, an igniter comprising an lgnition tongue of lesser diameter than the aperture extending from said aperture into the cylinder, and a head of greater diameter than the small end of the aperture engaging the outer surface of the cylinder head and detachable means for holding the igniter in place with the hea pressed against the cylinder head.

In an internal combustion engine, a cylinder head having an inwardly flaring aperture therein, an igniter arranged in said aperture, said igniter-comprising a head of larger diameter than the small end of the aperture and bearing against the outer surface of the cylinder head, a neck fitting the cylinder head adapted to press the igniter head against the cylinder head.

In testimony whereof, We have hereunto set our hands at Sacramento, California, this 20th day of June, 1913.
